# Musthave for everyone who uses dapps
DeNet Pass will give you access to download and view NFTs that are staked in the DeNet ecosystem.
Defender function will warn you if the content hash on the site is not original. It checks hashes of content and protects users from negative updates from hackers or developers (for example, phishing attacks). For example, if you browse Uniswap and their team creates an update, the extension will notify the user about the update.
Second example — you get a link from the official channel and save it.You can open the link and be sure that the website will not be modified.
Third example — you open a new site for you and Defender gives you the info about the number of users who approved this version of site. If you make a typing mistake in the URL and get on a phishing website, you will know that this site is not using Defender or see the number of proofs for this site. You also will see the date of first proof page creation and versions list.
Fourth example — you simply don’t like last design update from any dapp team, and you may select last used version to browse.
# Blockchain basics
Every time when users open new tabs or pages, our extension runs a comparisong algorithm. If a website is updated or not registered in user history, the extension sends requests to check hash with external service.
External service tries to mine a new block of private blockchain with next algo: sha256(app sha256 + page sha256 + user address + block) and if result is less than current difficulty, new block will be mined. Average block time ~ 1min.
# Reputation and reward
Every new block’s top 100 users by rep will get a part of 2 dUSDC in proportion to their reputation size. Also, the user who won the challenge will get 0.01 reputation point.
Reputation grows up when you approve new websites, and decreases when you randomly open websites without other proofs (more than 1 day after first opening) from the community.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
